Description: TOXCAST_PhaseIII is the full set of 4584 chemicals available for screening in the current Phase III of the ToxCast screening program, consisting of the major portion of the Phase II testing library (excluding 37 chemicals due to unavailability or sample problems), and the newly added ph3 chemical subset. Testing Phases I and II of the ToxCast program are closed; hence the inventories associated with those historical data (i.e., ph1v1, ph2v2, e1k) are static and unchanging. ToxCast Phase III is currently underway; hence, chemicals may be dropped due to depleted stock, and the newly added ph3 inventory (current as of 4/11/2017) may continue to expand into less well-represented areas of chemistry and biology. In addition, whereas Phase III offers the possibility of screening up to 4584 chemicals, typically far fewer chemicals are undergoing more targeted screening. For more details, see TOXCAST
